Why are you not allowed to turn off the road now?

In this situation, you are not allowed to turn off the road because of the red car already on the road. According to German traffic rules, you may not cut in front of or obstruct other vehicles that have the right of way or are already occupying the part of the road you want to move into. The red car represents oncoming traffic that is close and must be given priority. Turning off the road or attempting to overtake while such traffic is present is forbidden because it creates a dangerous conflict and can cause accidents. Always wait until the road ahead is clear and there is no immediate risk from oncoming vehicles before turning or overtaking. This ensures safe and orderly traffic flow.
